eGPU experiences [version 2.0]

[Tech Inferno Fan]

It actullay is possible its just that not alot of people are doing it i am taking the risk so i just need to know what is the most powerful gpu i can run

Unfortunately your AMD 4555M CPU is really pretty poor performing sitting between a 2nd-gen low-end i3 and 1st gen i5: PassMark CPU Lookup . Furthermore, your system has no expresscard slot so would require a more cumbersome mPCIe implementation. It's also a risk as there are no previous implementations to work off. Even if it did work the slow CPU and lack of Intel iGPU would mean no internal LCD mode (Lucid Logix/Optimus) nor x1 pci-e compression (Optimus) so overall would give unsatisfactory performance.

Therefore I'd strongly recommend you consider offloading the system for a budget Sandy/Ivy Bridge system such as a 15" HP 4530s, Lenovo E520/T520 or Dell Vostro 3550/E6520 or even a 12.5" HP 2560P/2570P. Best being systems capable of being upgraded to a i7-quad. All of those have an iGPU and an expresscard slot so when paired with PE4L-EC060A + NVidia Fermi/Keplar video card will give great x1.2Opt performance and internal LCD mode. Those systems can be had for low $$ on ebay.

@Diarek

One Question, have you the Setup 1.x?

No, i don't have that one, that why i used Magma Solution, it did works once so i figure it is unnecessary to get Setup 1.x. Maybe when i go for that x2, but that's for later.

Hi guys! First of all thank you to Nando and the rest of the community for keeping this scene alive. It's encouraged me to go ahead and try an eGPU build of my own! I haven't built up a PC since my 486 all those many years ago (!) so doing the research in preparation for this brought back so many memories.

My planned setup: 14" HP ProBook 6460b i5-2520M @ 2.50GHz 16.0 GB, 3x ViewSonic VX2453, EVGA GeForce GTX 670, DIY eGPU (PE4L-EC060A), Corsair CX600M, SilverStone SG02B-F

I thought briefly of upgrading my motherboard to an 8460p and upgrading my CPU to a Quad Core, but thought I'd try it with the 6460b first and see how far the Dual Core i5 can go. Any other 6460b owners out there?

Components are on the way hopefully in time for a nice gaming session this weekend! I'll post up a pic once it's up and running, but in the meantime wish me luck!

Welcome to the community!

I'm a dual core i7 (2620M) user and get pretty solid performance. Our CPUs are only 0.2 GHz apart, so our performance should be decently comparable.

Everything you have listed looks good. Good luck with your build!

[kaladeth]

@Ivyx - Awesome case! Bring on those tables man.

@angerthosenear - Thank you! I checked out your setup... 5+1 displays wow! Does nVidia Surround work across all those? Also what are your benchmark scores?

[angerthosenear]

@angerthosenear - Thank you! I checked out your setup... 5+1 displays wow! Does nVidia Surround work across all those? Also what are your benchmark scores?

I take it you saw the pictures in my 'General eGPU guide and Fujitsu T901' page (the one linked in my signature)?

I guess technically it would be 4+1+1 or 4+2. 4 displays are eGPU driven, the left most is driven my the iGPU along with the internal laptop screen.

I don't use Surround. I can't really, none of my monitors are the same resolution. The three on my monitor mount on the right are (left to right):

1400x1050

1920x1080

1280x1024

I need to redo benchmarks now that I have finally resolved my thermal issues with my laptop that were causing severe thermal throttling. This I'm sure hurt my benchmarks significantly.

Here is one of my older ones that I bookmarked:

NVIDIA GeForce GTX 660 Ti video card benchmark result - Intel Core i7-2620M Processor,FUJITSU FJNB231

I might re-benchmark tomorrow. Not doing Vantage, could never get that to work. Not even going to bother trying again.

I'm currently running it with iGPU+dGPU+eGPU under Windows 8.1 with a DSDT override and 36bit compaction around my eGPU. I will benchmark with 3DMark06 and 3DMark11 configured as iGPU+dGPU+eGPU and iGPU+eGPU.

[jot23]

The best score I've achieved with 2570p i5-3210m and GTX660 eGPU:

NVIDIA GeForce GTX 660 video card benchmark result - Intel Core i5-3210M Processor,Hewlett-Packard 17DF

GTX660@1241MHz core/6008Mhz memory (effective).

I wonder what is the drawback for our 3dm11 scores? It's not as demanding for PCIe bus, as some games like Crysis 3 or Assassins Creed III. The GPU score should be a lot higher.

But your problem with error 12 is, that your dGPU is not disabled. So if Magma Solution can disable the dGPU try it, otherwise try Setup 1.x to disable the dGPU.

The best score I've achieved with 2570p i5-3210m and GTX660 eGPU:

NVIDIA GeForce GTX 660 video card benchmark result - Intel Core i5-3210M Processor,Hewlett-Packard 17DF

GTX660@1241MHz core/6008Mhz memory (effective).

I wonder what is the drawback for our 3dm11 scores? It's not as demanding for PCIe bus, as some games like Crysis 3 or Assassins Creed III. The GPU score should be a lot higher.

If you peruse the DX11-centric leaderboard, you'll see your 3dm11 score is within the expected range.

A GTX660Ti would net you about a ~1.5k increase in the 3dm11 GPU score. That's because a GTX660Ti is a substantialy more powerful with it's +40% more processing units (960 -> 1344) as detailed at AnandTech | The NVIDIA GeForce GTX 660 Review: GK106 Fills Out The Kepler Family .

A GTX660Ti's architecture has more in common with a GTX670 than with a GTX660. NVidia could have named a GTX660Ti as GTX670 and a GTX670 as a GTX670Ti to lessen the confusion.

I consider the GTX660Ti the minimal standard required for a high performance eGPU implementation.

1. neither have an expresscard slot. You need to ensure that both have an accessible mPCIe slot.

2. you'll need a PE4L-PMxxxA 2.1b adapter. They provide a Gen2 link when using the mPCIe slot. Request they provide 15s PCI Reset Delay switch option. Currently it's only 0/500ms/6.9s. You'll need the 15s for the DV6-7000.

3. For internal LCD mode to work along with x1 pci-e compression when using a NVidia Fermi/Keplar card, an active primary Intel iGPU must be present AND your system's NVidia dGPU must be disabled. Check for the former in Device Manager. Check the latter in your BIOS. If no facility to disable the dGPU exists in the BIOS exists then use Setup 1.x to do it. Recommend a GTX560Ti or GTX660+ card. GTX650 cards are inconsistent with their pci-e config space usage. There are quite a few that require large 256MB pci-e config space windows which can add additional complexity to getting them running with 4GB or more of system RAM.

Lastly, if you go ahead with the eGPU implementation then please report your results so we can add you to the Implementation table as neither the Y580 or DV6-7000 are currently represented. Thanks.

Yea i will get the HP dv6 and i will document pics on what i did and how i did it. I am currently selling this laptop because it sucks! well kinda. anyway Cheers! I will be back soon!

[Diarek]

But your problem with error 12 is, that your dGPU is not disabled. So if Magma Solution can disable the dGPU try it, otherwise try Setup 1.x to disable the dGPU.

It is as you said, i encountered error 12 before my PE4H went to flame and i has successfully employed Magma FullDriver to overcame it, but problem is now my system cant even detect the eGPU to begin with and that is where i need your guys help.

@Ivxy

These tables are pretty impressive. Thank you very much for your effort!

@All

In the meantime, I got my egpu setup running.

Notebook: Dell latitude e5430 (chipset HM77)

Adapter: pe4l 2.1b with 60 cm cable @ express card adapter

GFX: Palit Geforce GTX 460 (to be replaced soon)

It was really exhausting to get it running, here is what had to be done.

• a dsdt override to extend the pci bus address space to 36 bit, card still failed with error 43
  
• bought setup 1.3 (thanks nando!) and played around a bit..
  
• in the end the following configuration worked: GEN1 speed and PCI Compaction Endpoint 56.xGB (my created address space)
  

If I use GEN2 speed the device is shown in the device manager without any exclamation mark. But GPU-Z just shows the card, no MHz etc... And it's just not working. Nvidia system panel won't open up saying: "no nvidia gpu attached"

Is my express card slot not capable of running GEN2 speed? Is that possible?

Is my pe4l adapter malfunctioning??

Could the problem vanish with another graphics card?

Any help appreciated!

After considerable effort it's good to hear you got it all working, though at x1.1Opt speed

You list exactly the likely reasons for Gen2 not working. Now given there have been success stories with PE4L 2.1b + Sandy/Ivy Bridge Latitudes at Gen2 (E6230, E6520/E6530) it's unlikely that the expresscard is the problem. More likely either the PE4L 2.1b or the video card. Khenglish had a GTX460 which refused to run at x1 2.0 on his E6520 but a GTX580 worked fine.

Testing another video card would be the first step in isolating the problem. If still works only at x1 1.0 speed then you have good evidence to suggest the PE4L 2.1b is faulty and request a replacement from BPlus.

I consider the GTX660Ti the minimal standard required for a high performance eGPU implementation.

Yes, of course, I considered buying 660ti, but 660 was way cheaper for me.

My 3dm11 score is very good for a 660 eGPU, but... I don't understand why we can't (mostly) get a score equal to the desktop one. In games, we see that sometimes the PCIe bus causes a huge performance drop, but as I mentioned, 3dm11 is way less demanding for the PCIe bus than those games (Crysis 3 "Welcome to the jungle" mission is a perfect example).

So, I just don't get it, how can we loose that much performance in 3dm11? What is the cause of it? The more powerful the card is, the bigger the difference. For example, GTX760 scores about 1k points less than it should.

Ok, thanks.

I will try another card. By the way: Never buy a Palit card, it was as loud as a vacuum cleaner.. Can't really recommend it!

That happens, when you only look at the price

This product would support at most x1.2Opt as it uses only one mPCIe slot. I have my doubts that it would actually support a 2.0 link due to the HDMI connector it uses which appears to be an issue with other similar products.

Hey dj_khalsa,

nice case, since your Zotac GTX 680 is more or less equal with my Zotax GTX 770, I I would like to know your benchmark results. If it is possible...

Hello,

I've just got a second hand 2560p and a 7970.

I had a 4850 which was recognized in my win 7 and gave me a error 12. I didn't try it with setup 1.x

because I wasn't sure if I would get a Nvidia or a AMD card. But I guess it means that PEAL 2.1b is working.

Now I've got a used HD7970 and setup 1.30 test2b.

The card is recognized in win7 and egpu setup but give me error 43, fans seem to run slow (probably standby/idle).

My 400W psu (24A 12V rail) didn't have a 8 pin nor a 6 pin connector, so I'm using two molex converters

Default booting mbr2 gives me a [mbr2] HD2->HD1 something and then some [uEFI] error, booting mbr/bootloader brings me to startup selection menu again where I choose win7. Does it matter what I choose if I eventually load win7?

I tried latest amd driver 13.9 and 13.2 beta 5 (which some here used with a HD7970), and setting gen 1 and 2 in BIOS. SW2 is set to 2-3 (non 1x..) since it doesn't detect with 1-2.

Any ideas why I get that error?

Before compaction and after(with using "all but option", I also tried only igpu and egpu which gave me 64MB):

Thanks ahead,

Paul.

Thank you for the feedback RE: Setup 1.30. I'll set it back to default to 'chainload mbr' in the next test version. That or 'chainload bootmgr' is what I'd expect would get you back into Win7/8.

The problem with your system reporting nonsense in GPU-Z is related to hotplugging the AMD 7970. If you use the Setup 1.x VIdeo cards->Show state->ATiAMD-atiflash, it too will probably report no VBIOS.

So need to experiment in adding the video card to the system such that the VBIOS is reported.

Try setting SW1=3 (6.9s) on the PE4L. Power on the PE4L just prior to powering on the 2560. Hit F5 in Setup 1.x to get the eGPU detected. Does that do it?

Or else power on the PE4L and plug in the expresscard-cable end into the expresscard slot. Does that do it?

Or else plug in the expresscard cable-end into the expresscard and power on the PE4L. Does that do it?

I've requested that BPlus extend the 6.9s delay in next revisions as HP system have problems with 6.9s. You may consider setting a 15s delay with a capacitor change as shown at http://forum.techinferno.com/diy-e-gpu-projects/2109-diy-egpu-experiences-%5Bversion-2-0%5D-146.html#post58860 .

Hey and thanks for all your work!,

It worked once (AMD Radeon HD 7970 video card benchmark result - Intel Core i5-2540M Processor,Hewlett-Packard 162B) after my original post when I reconnected everything and played with the connector, but then I restarted and tried setting gen 2 in BIOS and it stopped working.

I'm not sure with the delay modification since I used to set it at 500ms delay, wait to boot selection, and power the card, that usually detected it on the start,

I could wait more if that matters.

Now I changed it to 6.x seconds and I start it with the laptop, go in setup 1.x, choose menu, it doesn't find the card yet, so I press f5, and again if needed and

after a couple of seconds it finds it.

I tried without PCI compaction and I get error 12 and non sense reading in GPU-Z. With PCI Compations I get error 43, good bios with some weird clock readings:

(not working, not working, working)

The card is lying and the connector seems to be a bit loose, my 4850 didn't work till I stood it up, but the 7970 is too heavy for it to stand up

without the back falling a bit. The first time it worked was also after it stopped detecting at all and I played with the EC2C part of it.

1) Does the PE4L use only the first part of the PCI connector or also the cut part which sometimes is in a bit of a angle?

2) If its the EC2C end what can I do?

3) Can you unplug the hdmi cable on the express card? If not, is it durable to keep pluging/unpluging the express port everyday after I get this working? if not

is there a express card extender to relief the stress?

4) It doesn't usually doesn't detect the card when I set gen 2 in bios, or SW2 to 1E. So should I keep using SW2 on 1E? or try 2x,4x...? What does that do?

Thanks ahead, Paul.

Hey dj_khalsa,

nice case, since your Zotac GTX 680 is more or less equal with my Zotax GTX 770, I I would like to know your benchmark results. If it is possible...

Sure, however since my RAM and Processor are limited, the overall score is not that high, but the graphics score is respectable (I guess )
